我有一种情况，我想从Libreswan连接到DRG。我遵循了官方文档： https://docs.cloud.oracle.com/iaas/Content/Network/Concepts/libreswan.htm 隧道已建立，但没有流量在流动。 我的配置是：
config setup
plutoopts="--perpeerlog"
protostack=auto
conn oracle-tunnel-1
left=DRG tunnel 1 public IP address
right=192.168.12.4
rightid=Libreswan public IP # See preceding note about 1-1 NAT device
authby=secret
leftsubnet=0.0.0.0/0
rightsubnet=0.0.0.0/0
auto=start
mark=5/0xffffff1 # Needs to be unique across all tunnels
vti-interface=vti1
vti-routing=no
encapsulation=no
conn oracle-tunnel-2
left=DRG tunnel 2 public IP address
right=192.168.12.4
rightid=Libreswan public IP # See preceding note about 1-1 NAT device
authby=secret
leftsubnet=0.0.0.0/0
rightsubnet=0.0.0.0/0
auto=start
mark=5/0xffffff2 # Needs to be unique across all tunnels
vti-interface=vti2
vti-routing=no
encapsulation=no
隧道打开：

但是没有流量在流。
有什么想法吗？
